How to Do the Military Sleep Method

The military sleep method is a relaxation sequence that spread from a 1981 book called Relax and Win: Championship Performance, where Lloyd Bud Winter described a routine taught to naval aviation cadets. It is the most-shared sleep technique on the internet and it is also the most badly written-up one: the versions that go viral usually list four steps, drop the part that matters, and attach a claim about two minutes that nobody has tested.

Here is the whole thing, in order, and then what the evidence actually supports.

The sequence

Lie on your back, or on your side if that is how you sleep. You are not trying to fall asleep during the steps. You are trying to arrive at the end of them with nothing left holding tension.

1. Your face. Start at the forehead and let it go slack. Unclench the jaw and let it hang very slightly open. Let the tongue sit loose in your mouth instead of pressed to the roof of it. Relax the muscles around the eyes — there are a lot of them, and they are the last thing anyone thinks to relax.

This step is first for a reason. The face is where people hold tension without noticing, and a tense face is the thing that keeps signalling alert after the rest of you has given up.

2. Your shoulders, then your arms. Drop the shoulders as far as they will go — most people find they were holding them a couple of centimetres higher than necessary. Then let the upper arm go heavy, then the forearm, then the hand. One side, then the other, rather than both at once.

3. Your chest. Breathe out, long, and let the chest stay down. Do not hold it there; just stop lifting it.

4. Your legs. Thigh, calf, foot. One leg, then the other. Heavy, not placed.

5. Ten seconds of clearing your mind. This is the step the short versions cut, and it is the step doing the work. Winter’s suggestions were to hold one still image — lying in a canoe on a calm lake with blue sky above, or in a black velvet hammock in a completely dark room — or, if images will not come, to repeat don’t think, don’t think, don’t think for about ten seconds.

6. If you are still awake, go back to step one. Nobody says this and it matters. The routine is a routine.

The claim you should not believe

Almost every write-up says this method puts you to sleep in two minutes, and that it worked for 96% of pilots after six weeks of practice. Both numbers come from the same 1981 book, and neither is from a controlled trial. There is no randomised study of this specific sequence with those results.

That does not mean the technique is nothing — and this is where a fair account is more useful than an enthusiastic one.

What the method actually is, mechanically, is progressive muscle relaxation with a short imagery step on the end. Progressive muscle relaxation is well studied for falling asleep: it appears across more than thirty randomised trials of relaxation techniques for sleep onset, and relaxation training is one of the components inside CBT-I, the first-line treatment for chronic insomnia. So you are doing something with real support behind it, wearing a headline that oversells it.

The honest version: this is a well-evidenced relaxation technique with a badly-evidenced number attached. Expect it to help you unwind. Do not expect a stopwatch result, and do not conclude it failed when the first night takes twenty minutes.

Why it is harder than it reads

Reading a six-step sequence takes fifteen seconds. Running it in the dark is a different job, and it fails in three predictable ways.

You lose your place. By the time you reach the legs, you are checking whether your face is still relaxed, which means you have stopped relaxing your legs.

You rush. Each stage wants roughly fifteen to twenty seconds. Read from a list, most people give each one three.

You reach step five and think about your day. Ten seconds of a still image is an instruction that is very easy to agree with and very hard to do, and there is nothing holding the ten seconds for you.

All three are pacing problems, not comprehension problems. Which is why a voice that just tells you what to relax next, at the right speed, turns out to be most of the value.

Running it as a drill

Sleep Switch runs the military method as a guided drill on Android: a quiet voice takes each stage at a set pace, so you are not remembering the order or timing yourself, and the screen goes dark on its own when the drill ends. It is free, at every length up to fifteen minutes.

The app labels the technique with how well studied it is, which in this case means “well studied” for the relaxation mechanism — not for the two-minute promise, which it does not make anywhere.

If the military method is not the one that works for you, the same app carries eight others, including the cognitive shuffle for a head that will not stop generating thoughts, and 4-7-8 breathing if the problem is more body than mind.

If it does not work

Two things worth knowing.

The first is that relaxation techniques are trained skills. The trials that show an effect train people for weeks. Three nights is not a fair test of anything.

The second is that if you are lying there for a long time, the technique is not the right tool at all. Being awake in bed for long stretches teaches your brain that bed is a place where you lie awake — and the fix for that is stimulus control: get up, go somewhere dim, come back when you feel sleepy. It is unintuitive, it is the best-evidenced thing on this entire subject, and no amount of relaxing your face substitutes for it.

And if the bad nights have been going on for weeks rather than days, that is a conversation with a doctor. Chronic insomnia has a real treatment — CBT-I — and it is more effective than anything you will find in an article.
